Bitser is free windows software for managing archives and backups similar to
WinZip, 7-zip and WinRAR but with an alternate user interface. Bitser's interface is built around the file system with explorer style views, and features similar to those found in backup applications. All underlying archiving functions are performed using the open source
7-zip compression software and therefore all major archiving formats are supported. Bitser also provides a password manager and MD5/SHA checksum calculator to verify file identity. Bitser is free software and can be downloaded here.
